Web1 de jul. de 2024 · Controlling overestimation bias. State-of-the-art algorithms in continuous RL, such as Soft Actor Critic (SAC) [2] and Twin Delayed Deep Deterministic Policy Gradient (TD3) [3], handle these overestimations by training two Q-function approximations and using the minimum over them. This approach is called Clipped Double Q-learning [2]. WebDouble Q-learning (van Hasselt 2010) and DDQN (van Hasselt, Guez, and Silver 2016) are two typical applications of the decoupling operation. They eliminate the overesti-mation problem by decoupling the two steps of selecting the greedy action and calculating the state-action value, re-spectively. Double Q-learning and DDQN solve the over-
WebDouble-Q-learning tackles this issue by utilizing two estimators, yet re-sults in an under-estimation bias. Similar to over-estimation in Q-learning, in certain scenar-ios, the under-estimation bias may degrade per-formance. In this work, we introduce a new bias-reduced algorithm called Ensemble Boot-strapped Q-Learning (EBQL), a natural extension Web12 de jun. de 2024 · Inspired by the recent advance of deep reinforcement learning and Double Q-learning, we introduce the decorrelated double Q-learning (D2Q). Specifically, we introduce the decorrelated regularization item to reduce the correlation between value function approximators, which can lead to less biased estimation and low variance .
